Dealing with Valkyrie V360 MERLIN coil whine and noise?
Every time the battle got intense, this piercing electronic whine would kick in, and my anxiety just spiked. Compared to other AIOs, the Valkyrie V360 MERLIN pump runs incredibly fast, but under a 180W load, the coolant temp was jumping between 42-48℃, causing the fans to ramp up and down constantly. I tried locking the pump at 50% in the software, but the CPU shot up to 98℃ immediately—totally unacceptable. I went back into the BIOS, switched the pump to PWM dynamic mode, and set the trigger threshold to 65℃. Using a decibel meter, I saw the noise drop from 45dB to around 32-35dB. I actually hit a snag where the pump started cavitating because the speed was too low, so I had to bump the minimum floor back to 2000 RPM. Now the CPU stays between 72-78℃. The whine is completely gone, and the system response feels way more tactile.
